BUILDING ROOF.

Application led March 1, 1926. Serial No. 91,435.

My invention relates to improvements in"l building roofs, and moreparticularly to pitched roofs of various kinds. The object of theinvention is to produce a relatively inexpensive tile root1 whichutilizes the principle of the corrugated sheathing, is less expensivethan the heavy clay tiles, and makes a permanent, weather-proof andfire-prooi` roof, and at the same time is exceedingly handsome. It isrecognized that generally,

in building, the roof is an extremely important part, and can be madeone of the handsomest parts of the structure, and my invention has inmind the production of a handsome roof as well as to make a roof which1s tight, durable, weather-proof and {ire-proof, and easily laid.Asbestos-cement corrugated rooing is generally made from Portland cementhaving more or less asbestos fibre incorporated with it, and is commonlylaid in long sheets or slabs which, for residences, would be ratherunsightly. My imf provvement comprises making slabs of this generalcharacter but in short lengths forming tiles, and perforating thesetiles in such a manner that they can be securely and readily fastened tothe deck or support, and will have all the fastenings concealed andcovered in such a way 'as not t0 be subject to the action of the weatherand as not to mar the appearance of the roof. These tiles can be laid inshingle fashion, and the exposed lower portions can be shaped as desiredto suit the 'fancy of the maker. Furthermore,

in producing these shorter lengths, I form or break the long slabs intothe shorter tiles in such a way as to produce rugged lines which satisfythe aesthetic sense, and produce a much better light and shade electthan would be the case`if there were smoothmechanical cuts or endformations. Furthermore, my invention contemplates piercing the tiles insuch places as to greatly facili tate layingthem, and in having theholes at the crests -o the corrugations where the drainage willnaturally be away from the astenings, thus keeping them dry and notsubject to rust. In many such structures the nails areplaced so that thedampness reaches 5o them, rust follows, and the adjacent and lowerportions of the roof are badly discolored. These and other advantages ofmy improved roof will appear more clearly from the description whichfollows.

5s Reference is to be had to the accomn panying drawings formin'g a partof this specication, in which similar reference characters indicatecorresponding parts in all the views.

Figure 7 is a broken planillustrating a further step in laying a roof.

The roof embodying my invention is made of tiles 10 which arerectangular and nearly square by preference, although the lower orprojecting edges may be scalloped or designed to suit the taste. Eachtile l() is provided with a nail hole 11 near the upper left hand corneras viewed in Figure 5, and a nail hole 12 near the lower right hand corner. It is also provided with holes 14 and 14 near the upper edge, thehole 14 being throughthe same corrugation as the hole 12, and the hole14 being through the neXt corrugation to the left. It will be noticedthat these nail holes are adapted to receive fastening nails 13,V andthat they are all made .through the crests of the corrugations, so

that when the tile is laid and a nail 13 driven through any hole, thenail head will be at the crest of the corrugations and any water thatmight otherwise reach the nail head will drain from it so as to preventcorrosion and discoloration as above noted.

I prefer to have the tiles with rugged ends, and especially with arugged or rough lower. end, as this is the only edge that shows afterthe tile is laid, and gives a much better and more aesthetic effect thanif a smooth mechanical cut were made. To this end a long slab of thematerial is cut on opposite sides slightly at the crests of thecorrugations, as shown at 15 in Figure 4, and then broken. In breaking,the cleavage will follow the cuts 15, but the main end portion will`appear rough as shown at 16 in Figure 4, and when laid on a roof, the,parts 15 will not show.

When the roof is completed it can be covered at the highest pointorvridgepole with caps 17 or the like as usual.

The tiles are laid in the general manner otI laying shingles to form aroof, that is they are arranged to break joints, and laid in rows frombottom to top, and it is better to work from left to right. In Figures 2and 3 I have shown how each row is laid. A tile 1() is fastened in placeat the left hand of the row by nails 13 which are driven only throughthe holes 11 and l2. The next tile to the right is then laid with itsleft hand corrugation a overlapping and nested upon the righthandcorrugation b of the first tile. This brings the hole 11 of the secondtile in registry with the hole 14 of the first tile. A nail is thendriven through the hole 11 of the second tile and 14 of the first, andalso through the hole 12 of the second tile. rIhis operation is repeatedon all the tiles in the row. When the second row 10 of tiles is laid,the first tile to the left is made to overlap slightly the left handtile of the first row, and is placed a little to the left of said tile,and with its right hand edge at the lower part in abutment with theIleft hand edge of the second tile of the first row, as shown at 0. Thisenables the parts to be laid very iat and snug, but in Figure 3 I haveshown the several tiles somewhat separated, in order that their relationmay be better seen. The upper lefthand tile 10a being arranged as shownwith its corrugations nested upon those of the tile below, is thenfastened by driving a nail 13 through the hole 11 of the left hand tile1()a and through the hole 12 of said tile and the hole 14 of the tile 10below. The next tile 10a to the left is then laid as already describedwith reference to the left hand .tile 101 and to the tiles below. Thusit will be seen that as the work rogresses, a nail is driven throughlevery ole in each tile, but the nails -are all concealed, and the tilesby their abutting and nested relation held against any lateraldisplacement by the corrugations themselves, thus relieving undue strainon the nails. In this manner a very tight sound root is made which willbe. as handsome as a roof made of heavy clay tiles, and will be far lessexpensive and Amuch lighter. It will be of course understood that thetiles may be colored to suit the taste.

I claim 1. A building roof composed of approxiinatelv square corrugatedtiles, each having nail holes through the extreme right and leftcorrngations near the upper edge, a holealigning with said holes thru acorrugation lying second from the edge, and a hole through a sidecorrugation near the lower corner and in alignment with a nail hole nearthe upper corner, and with the tiles laid so that in one row the lefthand corrugation of one tile overlaps the right hand corrugation of thenext, and with the second row offset with relation to the rst row, withthe lower edges of the tiles of the side corrugatons. and one of saidholes being through the crest4 of a second corrugation nexta sidecorrugation and with a fourth hole near the lower corner and through aside corrugation, whereby the several tiles can be nested, overlapped,and fastened to conceal the nails in the nail holes and expose the loweredges of the tiles.

In testimony whereof, I have signed my name to this specification this25th day of February, 1926.
